The world of cryptocurrency mining just witnessed a major milestone with the launch of the Bitdeer SEALMINER A3 series. Officially introduced on September 16, 2025, this advanced lineup of Bitcoin mining rigs is engineered to deliver cutting-edge performance, groundbreaking efficiency, and flexible cooling options designed for both small miners and large-scale industrial farms.
With hash rates reaching up to 660 TH/s and industry-leading power efficiency as low as 12.5 J/TH, the SEALMINER A3 models are positioned to transform the economics of Bitcoin mining, reducing operational costs while maximizing returns.
What Makes the SEALMINER A3 Series Special?
Bitdeer’s SEALMINER A3 family comes in four variants, tailored to different deployment needs:
- SEALMINER A3 Air – 260 TH/s at 14.0 J/TH (air-cooled)
- SEALMINER A3 Pro Air – 290 TH/s at 12.5 J/TH (air-cooled, optimized for efficiency)
- SEALMINER A3 Hydro – 500 TH/s at 13.5 J/TH (liquid-cooled)
- SEALMINER A3 Pro Hydro – 660 TH/s at 12.5 J/TH (liquid-cooled flagship model)
Each machine is powered by Bitdeer’s proprietary SEAL-series ASIC chips, developed in-house to ensure tighter integration of hardware, software, and energy management.

Key Features and Advantages
- Industry-Leading Energy Efficiency
With efficiency rated as low as 12.5 joules per terahash, the A3 Pro models rival the best miners on the market. For mining operations w electricity is the largest expense, this improvement can significantly boost profit margins. - Flexibility in Cooling Solutions
Air-cooled models are ideal for smaller setups, while hydro-cooled versions provide extreme density and near-silent operation for large farms. - High Power Density
The flagship A3 Pro Hydro delivers 660 TH/s in a compact footprint, allowing operators to maximize hashing power without expanding physical space. - Next-Generation Chip Technology
Built on Bitdeer’s SEAL chip roadmap, the A3 reflects years of R&D that started with the earlier A1 and A2 series and now culminates in advanced efficiency and performance metrics.
Comparing SEALMINER A3 With Competitors
When compared with Bitmain’s Antminer S21 series and MicroBT’s WhatsMiner M60 family, the SEALMINER A3 models hold their own in both efficiency and density. While many competing miners operate around 15–18 J/TH, the A3 Pro Hydro at 12.5 J/TH gives miners a stronger competitive edge, particularly in regions w electricity costs are high.
Global Pricing Insights
Pricing for the Bitdeer SEALMINER A3 series varies depending on the reseller, shipping region, and local import duties.
- United States: Early reseller listings suggest prices starting around $4,000–$5,000 USD depending on the model and configuration.
